Summary module description:

Aims:
This module develops the concepts introduced in CH1FC1 and provides a comprehensive background in chemistry for biological and food scientists. It has a specific emphasis on the chemistry required for the life sciences and the material is illustrated in case studies and workshops relevant to these students.

Assessable learning outcomes:

Students should have a good understanding of all the topics outlined below. In addition they should appreciate the relevance of the material to applications in the life sciences and especially food science. Students should be able to perform calculations and solve problems on any of the areas covered.


Additional outcomes:

Students will develop confidence in applying the language and terminology of chemistry in biological situations, will improve their numeracy skills and have opportunity for small group work in the problem solving sessions.

(P.B. Cranwell, 2 lectures, 1 workshop). 


Brief description of teaching and learning methods:

Each session consists of 2 lectures and one workshop on related topics. The lectures outline the theory and applications and the workshops involve practice on problem solving related to topics from chemistry and the life sciences. Each weekly session is assessed by multiple choice in-class tests. Attendance is compulsory at all sessions.


Contact hours:
  Autumn Spring Summer
Lectures 20
Seminars 10
Guided independent study 70
       
Total hours by term 100.00
       
Total hours for module 100.00

Summative Assessment Methods:
Method Percentage
Written exam 60
Class test administered by School 40

Other information on summative assessment:

Students will carry out short multiple choice tests throughout the term based directly on lecture material. Continual assessment by in-class tests in weeks 4, 9 and 11 of term will be 40% of final mark. Final exam (not multiple choice) will be 60% of final mark.


Formative assessment methods:
Weekly workshops with feedback on Blackboard and one to one with demonstrators and staff.

Penalties for late submission:
The Module Convenor will apply the following penalties for work submitted late, in accordance with the University policy.

  • where the piece of work is submitted up to one calendar week after the original deadline (or any formally agreed extension to the deadline): 10% of the total marks available for the piece of work will be deducted from the mark for each working day (or part thereof) following the deadline up to a total of five working days;
  • where the piece of work is submitted more than five working days after the original deadline (or any formally agreed extension to the deadline): a mark of zero will be recorded.

  • The University policy statement on penalties for late submission can be found at: http://www.reading.ac.uk/web/FILES/qualitysupport/penaltiesforlatesubmission.pdf
    You are strongly advised to ensure that coursework is submitted by the relevant deadline. You should note that it is advisable to submit work in an unfinished state rather than to fail to submit any work.

    Length of examination:
    1.5 hours

    Requirements for a pass:
    A mark of 40% overall.

    Reassessment arrangements:

    Reassessment will comprise of an examination worth 100%.
